Six hours post-hatch, large white turkey poults were inoculated intranasally with 5 x 10(7) cells of the W isolate of Bordetella avium. Three hours after inoculation and subsequently on days 7, 10, 14, 21, and 28 postinoculation, poults from infected and control groups were killed by cervical dislocation. Thymus, spleen, and bursa of Fabricius were removed, weighed, and frozen until assayed for norepinephrine (NE), dopamine (DA), and serotonin (5HT). B. avium infection caused a reduced concentration of NE, DA, and 5HT in the spleen, thymus, and bursa of Fabricius. The reduced concentrations of these monoamines in lymphoid tissues of diseased poults may be a normal response during the course of a disease or during the mounting of an immune response.

D008221 Lymphoid Tissue Specialized tissues that are components of the lymphatic system. They provide fixed locations within the body where a variety of LYMPHOCYTES can form, mature and multiply. The lymphoid tissues are connected by a network of LYMPHATIC VESSELS. Lymphatic Tissue,Lymphatic Tissues,Lymphoid Tissues,Tissue, Lymphatic,Tissue, Lymphoid,Tissues, Lymphatic,Tissues, Lymphoid
D008297 Male Males
D011201 Poultry Diseases Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild. Disease, Poultry,Diseases, Poultry,Poultry Disease
D001885 Bordetella Infections Infections with bacteria of the genus BORDETELLA. Infections, Bordetella,Bordetella Infection,Infection, Bordetella
D002060 Bursa of Fabricius An epithelial outgrowth of the cloaca in birds similar to the thymus in mammals. It atrophies within 6 months after birth and remains as a fibrous remnant in adult birds. It is composed of lymphoid tissue and prior to involution, is the site of B-lymphocyte maturation. Fabricius Bursa
D005260 Female Females
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D013154 Spleen An encapsulated lymphatic organ through which venous blood filters.
D013950 Thymus Gland A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.

D014422 Turkeys Large woodland game BIRDS in the subfamily Meleagridinae, family Phasianidae, order GALLIFORMES. Formerly they were considered a distinct family, Melegrididae. Meleagridinae,Meleagrididae
